INDIANAPOLIS — The Hoosier Lottery says the winning ticket for the Mega Millions jackpot worth an estimated $540 million was sold at a gasoline station in eastern Indiana.

Hoosier Lottery spokesman Dennis Rosebrough says the ticket for Friday’s drawing was sold at a Speedway station along Interstate 70 in Cambridge City, a town of about 2,000 residents 50 miles east of Indianapolis.

A person who answered the phone at that store directed calls to Marathon Petroleum’s corporate headquarters. A spokesman, Brandon Daniels, says the company has no comment.

Because the Speedway location is along a busy highway, Rosebrough says the person who bought the ticket may not be from Indiana. He says “we know the ticket was sold in Indiana, but being on I-70, who knows who bought it?”
